    I like using this item if I am in a hurry. It is fast and easy. I don’t know much about results yet as just started using it.

    Love!

    I love this serum! And I honestly just love all the products I use from Outset. It’s so hard to find skincare that is clean, has no fragrance, and that yields good results. But Outset skincare does all of that!

    Love it

    Love this serum! It has become a staple in my routine. Anti aging and works great before sunscreen/moisturizer
